Abstract

Embodiments of the invention include a device with stacked substrates. Conducting interconnecting structures of one substrate are bonded to conducting interconnecting structures of another substrate. A passivating layer may be on the conducting interconnecting structures between the substrates and may be formed by an atomic layer deposition process or a with a Langmuir-Blodgett technique.
